Expansive soils are soils that contain minerals such as certain types of clay that are able to absorb water. When the clay absorbs water, it will expand. The more water they absorb, the more they expand. Soils containing as little as 5% clay can exhibit expansive characteristics.
An S trap is a drain trap that looks like a letter “S” sitting on its side. The plumbing systems in most older homes used S traps on the drain lines under sinks, but S traps are now prohibited by code throughout the country because they are not vented.
In a back-fed breaker, the wires that are bringing the power into the panel are connected to the back-fed breaker just like they are connected to any other breaker. This means that the power is going backwards through the back-fed breaker and then to the main bus.
A ground fault circuit interrupter, also called a GFCI or GFI, is an electrical device designed to monitor current flow and upon detecting a ground fault (“leaking” current), to instantaneously open the circuit and stop the flow of electrical current.
In my career, I have seen just about every degree of settling and every foundation problem that a home’s foundation can experience. I have also discovered that there is a difference between normal foundation settling and serious foundation problems.
Over the years, exposed light bulbs in closets have been the cause of many house fires throughout the country, because the heat that they generate can cause things like clothing, paper, and cardboard boxes to ignite if they are too close. There are certain requirements to prevent this and keep your home safe.
There is a lot of confusion about grounding and bonding and the purpose of each. Sometimes, they are used interchangeably, but they mean different things, and they serve two different purposes. So, what is the difference between grounding and bonding?
Your home’s plumbing vent system is very important for the health of your home. It keeps nasty sewer gases out of your home, and it helps the drain lines to drain properly.
Double lugging is when two wires are placed under the same screw on a circuit breaker or on the neutral bus in an electrical panel. Double-tapping is normally done by a homeowner or a handyman who knows just the basics of electrical work.
What is current? What is voltage? What is the difference between voltage and current? How are voltage, current and resistance related? I will explain these concepts by comparing electricity flowing through a wire to water flowing through a water hose.
